This is perfect. The add says to kits for an 89’ flat, but I wonder if that is enough to have them two wide like the prototype.
Rob is right on. Flat cars referred to as all purpose 89’ are the type set up for either Trailers and/or container service, by the standard nomenclature. Flat cars are usually designated for the type of loading by their reporting marks such as TTX, TTWX, XTTX, JTTX and so on, at least in the 70’s and 80’s.
FYI, here is the Trailer Train list from an RMC magazine (August 1990) article on the subject listing the TT markings:
